Overview
The BYG20G is an ultrafast avalanche SMD rectifier diode manufactured by Diotec Semiconductor. It features a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage of 400 V. The device exhibits a typical reverse recovery time of less than 75 ns, ensuring rapid switching performance. Electrical characteristics include a forward voltage of less than 1.3 V at 1 A and a non-repetitive peak reverse avalanche energy rating of 20 mJ. Operating temperatures range from -50°C to +150°C.
Feature Summary
- Ultrafast recovery characteristics with minimal reverse recovery time for high-frequency applications
- Avalanche-rated capability allowing operation under inductive load switch-off conditions
- Robust surge current handling with high non-repetitive peak forward surge ratings
Applications
- High-frequency switching power supplies
- Inductive load protection circuits
- Free-wheeling diodes in motor control systems
Procurement Notes
Verify the specific suffix designation when ordering, as it determines the exact repetitive peak reverse voltage rating within the product family. Confirm that the required avalanche energy specifications align with the design's inductive load requirements. Ensure compliance with RoHS directives if applicable to the target market regulations.
Selection Notes
Select this component for designs requiring fast switching speeds combined with avalanche ruggedness. The DO-214AC package offers a compact footprint suitable for space-constrained PCB layouts. Consider the thermal resistance values when calculating heat dissipation for continuous operation at elevated ambient temperatures.
Part Context
This part belongs to the BYG20D through BYG20J series of ultrafast avalanche rectifiers. The series provides various voltage ratings to suit different circuit requirements while maintaining consistent current handling and recovery speed characteristics across all variants.
Replacement Considerations
Cross-reference with other ultrafast rectifiers offering similar 1.5 A current ratings and sub-100 ns recovery times. Verify that any substitute component meets or exceeds the 20 mJ avalanche energy specification and operates within the same temperature range.
